Figure 2 is a front elevational View of the same, with-the frontfcover removed. Figure 3 is an enlarged top plan view of the P cross-headguide rod guides, the wrist pin 320 and the oiling means for thesa'me. And Figure 4.is a perspectiveview of the arched deit is attached. I

Referringto the accompanying drawlngs flectingim'e'mber and the slotted tubes to which 25 for a detailed description of my invention,

the numeral 1 designates the base portion of casting having two vertical walls 2 80 shaft 6 Secured to the inner end of the shaft 6 is a gear 7 which meshes with a pinion 8 fast on a shaft 9 journaled in bearings 10 and 11 mounted in holes'in the upper portions of the casting walls 2 and 3 respectively. Fast-on the outer end of the shaft 9 is a large pulley 12 which receives a belt 13 that passes around a small pulley 14 secured to the armature shaft 15' of a heavy duty motor 16. The lati a casting formed with two spaced cylindrical guides, 23, 23 connected by a web 24 having 1929. Serial No. 377,643.

Formed on the rear end of the latter is a i downwardly projecting flange 26 contain ing a hole that receives the outer end of the wrist pin 21, the inner end of which is received by a hole in the upper portion of the web 24. (See Figures 1 and 3).

Between the outer ends of two flanges 27,

' 2-7 on the top projecting portion of the important and incidental objectsr 10 will be brought out in the following 'specifica- I tion and particularly set forth in the sub web 24, the-re is formed in said projecting portion. an oval hole 28 through which oil is discharged upon the wrist pin 21 from means to be hereinafter described.

The cross head guides 23, 23 are free to slide up and down over guide rods 29, 29, re-' spectively, secured between the top and bottom portions of the casing. When reciprocated by the connecting rod 19, the cross head, so guided, will actuate the upper section 30 of the pump rod. The latter has a reduced upper end which projects through a hole in' an arm 31that extends outwardly from the upper portion of the cross head. At its lower pump rod 30, by means of a nut 37, is a U piece 38 that is set on its side so that its top arm, which is longer than its other arm, will project over the rod. Connected to the free end of the U piece 38 is the upper end of a rod 39 to whose lower end there is attached the'plunger or piston 40 of an air pump cylinder 41. The latter is secured to a fitting 42 which is screwed into the water discharge portion 43 of the casting 44 which receives the upper end of the pump cylinder 34. Also communicating withthe discharge line 45 is a customary air chamber 46. Supported upon the latter is an automatic switch 47 forcontrolling the operation of the motor 16 to which it is connected by a cable 48.

For the purpose of automatically oiling the guides 23 and wrist pin 21, I provide the following means. Secured to the shaft 9 between the pinion 8 and the bearing 11, is

"1' -'50 a. rearwardly' projecting top portion 25. a metal disc 49. When the pump is in opera v tion, the gear 7, which turn-s in oil below its axis, will carry this oil up to the pinion 8. The rotating engagement of this pinion with the gear will splash this oil upon the disc 49. The latter, being also in rotation, will then whirl it to the top of the casing, where the following means direct it to the guides and wrist pin.

Projecting rearwardly from each guide 23, and communicating therewith, is a tube 50. Formed in the top portion of each tube at its rear end is a slot 51. Projecting up from the rear end of one tube and over and down to the rear end of the other tube, is a flat arched deflecting member 52. One end of this member uncovers the slot 51 in one tube, while the other end of the deflecting member covers the slot 51 in the other tube. Since he arched deflecting member is above the disc 49. part of the oil whirled upwardly by the latter will strike the under surface of said deflecting member. Part of this oil will be directed downwardly. by this deflecting member to the slot 51 in the tube 50 over which it extends. Through this slot the deflected oil will pass into the tube, through which it flows into its respective guide 23 to thoroughly lubricate it. Part of the oil thrown to the top of the casing by the disc -1-9 will drop through the uncovered slot 51 in the other tube 50, by which it is carried to its respective guide 23 to thoroughly lubricate it. Thus it is seen that both guides are automatically lubricated by the disc and associated means to permit them to slide freely upon the cross head guide rods 29.

Part of the oil which strikes the undersurface of the deflecting member 52, is directed by a tapered and downwardly inclined trough 53 to the oval hole 28 in the rearwardly projecting portion 25 of the web 24:- Through this hole the deflected oil descends to the wrist pin 21 to automatically and thor oughly lubricate it. The upper end of the inclined trough is secured to' the rear edge portion of the arched deflecting member 52 so that a maximum amount of oil will drop into it from the top of said member.

It is thus seen that the Wrist pin 21 as well as the guides 23, will be automatically and thoroughly lubricated by the disc 49, arched member 52, the tubes 50, 50 and the inclined trough 53 during the operation of the pump. Oil whirled to the top of the casing by the disc i9 will also lubricate other moving parts in the path of its descent.

Having described my invention, I claim:

1. In a deep well pump, the combination with a casing adapted to contain a lubricant, a pair of vertical guide rods, a cross head having sleeves reciprocable on said guide rods, operating means for said cross head extending into the oil in the casing, a'deflecting member carried by said sleeves, and means for whirling the lubricant from the bottom of the casing into contact with the deflecting member, for the purpose specified.
